SPECIFICATION forming part of Letters Patent No. 443,781, dated December 30, 1890. I Application filed July 19, 1890. Serial No. 359,332. (No model.)

To @ZZ whom t may concern: l

Be it known that i, GEORGE RODNEY MOORE, acitizen of theUnited States,residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Surface-Leakage Vater-Vessels, of which the following is a speciiication.

The object of my invention is to provide 1o porous water-vessels capable of graduated leakage over a Wide surface and for whatever uses such porous vessels may be found desirable, whether for desk use in offices or in other places and ways. To moisten the muoilage of envelopes or stamps, or ones fingers if need be, the convenience of a uniformly,- damp surface upon a roller or pad at easy touch is obvious. The construct-ion is very simple and easily understood. The vessel into which the Water is poured may be of any shape or size desired, provided it is all airtight excepting the surface intended for moisture, and this part is made of finely-perforated sheet metal, which perforations are covered with cloth or other fibrous and porous material to the extent desired for slowing the leakage from the perforations. 4When the vessel is filled, an air-tight stopper secures the inclosed Water, so that it can only ooze out through the cloth cover as fast as the air passes in the opposite direction through the same .pores to prevent a vacuum in the vessel. The principle involved is that air passes through dry cloth easier than when the same is wet. Thus the vessel is adj usted at pleasure by few or more layers of clot-h to the degrec of moisture or leakage desired by the operator, after which, by self-adjustment, it continues the same degree of moisture. Any tendency in the cloth cover to become dry is counteracted by a greater freedom of air through the pores into the vessel and a corresponding tendency for the wat-er to ooze out through the same pores, so that vessels made in this Way may stand for days with no perceptible change in the degree of moisture on the porous surface, until at last the water in the vessel is dissipated by slow evaporation from the surface. Any admission of air inward, whether by valve or otherwise, will 'pressure upon the vessel.

hasten the escape of water outwardly and uniformly over all its surface.

Figure l shows the water-vessel and framework supporting it in perspective, the vessel resting on small gudgeons, upon which it may 55 revolve. Fig. 2 is a vertical transverse seotion of the vessel and so much of the framework as may be seen on the line yy of Fig. 3. Fig. 3 is a cross-section of the Vessel in its frame-work, as seen on the line ir x of Fig. 2. 6o Fig. shows in cross-section an optional plan,

a kind of cup for a surface-leakage vessel, with water conveyed beneath a perforated plate covered wit-h cloth from a stand-pipe.

Similar letters refer to similar parts in all the figures.

A is the frame in which the vessel is horizontally suspended on small gudgeons c c.

B B are arms jointed to the frame at o. a and rigidly attached to the manual pressure-barb. 7o

C is the internal and the perforated part of the water-vessel. C is a removable head for filling the, same.

D is a manual air-valve; d, valve-stem and pressure-knob; d', closing-spring; c', valve- 75 guide and spring-support; E, firmly-attached cloth covering to the vessel; F F, rubber bands holding the same.

G is a supporting-roller to secu re any needed 8 H H is a spring turned up at each end and affording bearings for the journals of the vessel, so that in its normal state the vessel will be kept up and free from touch of G.

I is a cross-piece in the frame, to which H is fastened.

J is an outside and removable cloth spread over' the vessel and not inclosed by the rubber bands, so that for cleansing or change it is readily removed.

In Fig. 4, A is the vessel, akind of shallow cup, supplied with waterfrom the stand-pipe A2 through a duct a to the extent of the water-space a2. C2 is the perforated top of the cup; E', the cloth covering; J', the removable 95 spread. K is the filling-cap, air-tight. Lisa fianged ring screwed down upon the out edges of the leakage-cover to the cup.

To meisten the mucilage to an envelope by the surface-leakage ofthe vessel in the frame roo A, the gunnned side of the envelope should be slipped under the vessel above the roller G, and a slight pressure upon the pressurebar l) as the envelope is withdrawn imparts the required moisture. If more immediate wetness be required on the surface of the vessel when it is not without water, turn it up and toueh the air-valve for a moment and the desired result will be instantly obtained.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The horizontal perforated water-Vessel C, provided with the graduated fibrous leakage-cover E and aclose stopper C', substantially as and for the purpose herein set forth.

2. The perforated water-vessel C, provided with the graduated leakage-Cover E and stopper C', and removable cover J, substantially as and for the purpose herein set forth.

In combination,therevolvingperforated water-vessel with graduated surface-leakage,

and the frame A, with spring-bearings II Il and pressure-bar b, substantially as shown.
